The popularity of smartphone has drastically changed our daily lifestyle. Thanks to the progress of advanced fabrication technology, the performance of smartphone is enhanced by every year. There are more and more jobs carried by PC before can be easily done with smartphones. Among numerous components in a smart phone, there is no doubt that the central processing unit (CPU) plays a decisive role on its performance. For fabricating faster and more powerful chips, dimension scaling is a dominant way and the trend, the so-called Moore’s law, was already predicted by intel co-founder Gordon Moore in 1975 [1]. Surprisingly, the fabrication technology still follows the law and new generation of technology node will be continuously delivered [2]. In order to attract more orders from smartphone companies, keen technology node competition among main chip manufacturers in the world is in full swing and will not stop in the next coming years.
